PCIE Module
Perform the following steps to replace a PCI-E card in one of five hot-plug PCI-E modules
at the rear of the system while the system is on.
*Both the OS and PCI-E card must support the hot-plug feature.
Removing a Hot-Plug PCI-E Card
1. Initiate a hot-removal request by pushing the Attention Button on the corresponding slot.
The green power LED will blink to indicate the module is in a transition state. (To cancel
the hot-plug removal operation, press the Attention Button again within five seconds.)
2.
The power LED will turn off, showing that it is safe to remove the module. If not, it
indicates the request has failed (possibly due to client's software unwilling to relinquish
the device).
3. Push the red release tab located at the top left of the module to the right in order to pull
out the lever.
4. Use the lever to pull the PCI-E module out of the chassis.
